Arrhythmia News and Research RSS Feed - Arrhythmia News and Research
An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

UCLA team uses brain aneurysm treatment technique to treat irregular heart rhythms

For the first time, a UCLA team has used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients. [More]

Midwall fibrosis may increase likelihood of death in patients with nonischemic dilated cardiomyopathy

Detection of midwall fibrosis (the presence of scar tissue in the middle of the heart muscle wall) via magnetic resonance imaging among patients with nonischemic dilated cardiomyopathy (a condition affecting the heart muscle) was associated with an increased likelihood of death. [More]

Mirabegron reduces frequency of incontinence episodes in phase III trial

In a new phase III trial mirabegron, a β3-adrenoceptor agonist, given once daily for 12 weeks, reduced the frequency of incontinence episodes and number of daily urinations, and improved urgency and nocturia in adults with overactive bladder compared to those in a placebo group. [More]

Abell Foundation to award $50,000 to 3 Johns Hopkins researchers for medical inventions

Johns Hopkins' John Wong, Ph.D., has won a BioMaryland LIFE Award, and Ronald Berger, M.D., Ph.D., and Hien Nguyen, M.D., were awarded funds from the Abell Foundation, the researchers learned last week. Each of the winners will receive $50,000 to help develop their discoveries for clinical use. [More]

Experts to create first comprehensive model of human heart development

The walls of the human heart are a disorganised jumble of tissue until relatively late in pregnancy, despite having the shape of a fully functioning heart, according to a pioneering study. [More]
Physicians do not talk to patients about psychosocial impact and long-term risks of ICDs

Physicians do not talk to patients about psychosocial impact and long-term risks of ICDs

New research at Saint Louis University shows physicians do not talk to patients about the psychosocial impact and long-term risks of implanting cardioverter defibrillators (ICDs) to treat irregular heart rhythms, leaving them misinformed about how the device may affect quality of life. [More]
Study shows how gene mutations affect calcium pathway in arrhythmia

Study shows how gene mutations affect calcium pathway in arrhythmia

Using powerful X-rays, University of British Columbia researchers have reconstructed a crime scene too small for any microscope to observe - and caught the culprit of arrhythmia in action. [More]
Steroid therapy impedes Duchenne’s cardiomyopathy

Steroid therapy impedes Duchenne’s cardiomyopathy

Steroid therapy is associated with a considerable reduction in all-cause mortality and new-onset and progressive cardiomyopathy in patients with the debilitating X-linked disease Duchenne muscular dystrophy. [More]

Arrhythmia may confound heart failure treatment

Meta-analysis findings question whether beta-blocker treatment remains effective in patients who have heart failure with reduced left ventricular ejection fraction if they also have atrial fibrillation. [More]
Investigators discover two new genes associated with severe early-onset disorders of heart rhythm

Investigators discover two new genes associated with severe early-onset disorders of heart rhythm

A team led by Vanderbilt University investigators has discovered two new genes - both coding for the signaling protein calmodulin - associated with severe early-onset disorders of heart rhythm. [More]

Eletrocardiographic mapping nearing clinical utility

Electocardiographic mapping may offer a noninvasive and accurate alternative to a standard electrophysiologic study, say researchers. [More]

Function for Men safe and effective in fighting erectile dysfunction

Since sexuality is such an important part of who we are, men will always seek out effective erectile dysfunction remedies. So, it's no surprise that such massively marketed and potentially dangerous pharmaceuticals as Viagra and Cialis have generated an awful lot of attention -- as well as plenty of cold, hard cash -- for the big drug companies. Fortunately, the search for effective erectile dysfunction natural remedies mounted by the Antiaging Institute of California has brought us Function for Men. [More]

Researchers find new genetic differences in human hearts

Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments. [More]
